The IAU's names for exoplanets – and on most occasions their host stars – are chosen by the Executive Committee Working Group (ECWG) on Public Naming of Planets and Planetary Satellites, a group working parallel with the Working Group on Star Names (WGSN). [1] Proper names of stars chosen by the ECWG are explicitly recognised by the WGSN. [1]
An artist's rendition of Kepler-62f, a potentially habitable exoplanet discovered using data transmitted by the Kepler space telescope. The list of exoplanets detected by the Kepler space telescope contains bodies with a wide variety of properties, with significant ranges in orbital distances, masses, radii, composition, habitability, and host star type.
There are eight planets within the Solar System; planets outside of the solar system are also known as exoplanets. Artist's concept of the potentially habitable exoplanet Kepler-186f As of 14 February 2025, there are 5,834 confirmed exoplanets in 4,356 planetary systems , with 977 systems having more than one planet .

Kepler-1638b was thought to be a possibly habitable planet with a radius smaller than 2 R 🜨 after the validation. However based on the later measurement of host star parallax by Gaia, the radius of the planet was revised upward to 3.226 +0.201 −0.315 R 🜨, resulting in it being a ice giant like Neptune with poor prospect for habitability ...
